Second Lord Baltimore (1605-1675), proprietor of Maryland, eldest son of George Calvert.
At his father's death he was granted the charter of Maryland, thus becoming the first proprietor, by virtue of which office he was empowered to make laws.
This right he later abrogated in favor of the colonists, reserving only that of absolute veto.
Opposition at home prevented his accompanying the colonizing expedition of 1633, and during his long rule he never visited the colony.
Although his policy was always that of religious toleration, he came into conflict with the Jesuits over Indian grants of land to the latter and certain privileges claimed by them.
In 1659 he founded in London a Maryland mint, from which was struck the Lord Baltimore penny.
